To all whom it may concern: I

Be it known that ii, Gnome (l. lfimsrow,

a citizen of the United States, residing; at

Uuero, in the county of De Witt and State of Texas, have invented new and useful lui provements 'in Railway-thi'ossings, of which the following is e specification.

This invention relates to improvements in railway crossings.

In carrying out my inventionit is my purpose to provide a crossing which will. per unit the rolling stock to pass thcreovcr with out the jar and shock caused by the wheels passing the broken portions of the crossing over which the bearing faces of the Wheels pass in the ordinary construction of crossings.

ll also aim to provide a crossing which is connected with the main rails of the tract:

2e and auxiliary rails, Said auxiliary rails heing adapted to "form hearings for the flanges of the Wheels of the rolling stock, so that the bearing surface of the wheel is 'aiscd above the track proper, whereby the said rolling stock Will pass over the crossing; without shock or jar.

I also propose to provide an auxiliary track with a simple and cil'ectivc means whereby the same may he shimrncd to compensate for any wear which may-occur incident to the rolling stock passing thereover.

vVith the above recited objects, and others of a similar nature in view the invention re sides in the construction, combination and arrangement of parts, set forth in and. fallmg" within the scope of the armcndetl claims.

For the purpose of explaining the in vention the accompanying dr-aiiwiugrs illustrate av satisfactory reduction of the same to practiee but the important instrumcntalities thereof may be varied, and so it is to he understood that the invention is not liu'iitcil to the specific arrangement and organization shown and described.

In the drawings, Figure l is a, top plan -vieW of a double crossing" provided with my improvement. Fig. is a sectional view upon the line 2-2 of Fig. 1. Fig. 3 is a detail perspective view illustrating two oi the rightangularly arranged tracks provided with my improved auxiliary rail. is

Fl 1 n is a top plan view of a single crossing. Fig. '4' is a sectional view upon the line 7---7 l ig. (3. lfiig. 8 is a transverse sectional view of a modification oi? Fig. 4-.

lleii'crring' now lo the d awings in detail, the numeral 1 designates an ordinary cross ing. the some comprising longitudinally extending rails 2. and transverse intersecting rails "mth the rails 2 and 3 are, of course forn'uvl in sections, that spaces or open-- inn-s l and 5 are provided by the rails at the points of intersection, and the said openings are adapted to serve as passages through which the llancjcs oi the wheels oil? the rollinc siocl; may pass. in a crossing as justlesci'ilurd. it is ol. ions that the locating: laces oi the wheels passiugyover the cross-- iugr are not provided with a. continuous llttll'ing surface; that is, when the said \vhccls pass over the spaces or cut away portions 4- am! 53, a. shocl: oi: jar is oecasionet and when the said wheels pass over one of the rail sections to the second ii'ailscction in crmlaclino with the edge or end of the sec oud rail se tion both the hearing faces of the wheels and the ends of the ail sections of tlu: crossing are liable to damage, and as a consequence are rendered comparatively shorllivcd.

'lho numeral (3 designates the auxiliary rails which are secured to the inner faces 0'! the main rails. 'lheso rails taper gracefully From their oymosiitc ends and their points of connection with the main rails, and as a. conscoucucc the flanges of the wheels of the rolling stool: hcaiupon the said auxiliary rails and elevate the hearing): l -aces of the said. wheels to raise the same slightly above the main rails. The auxiliary rails provide continuous hem-inn surfaces and in no wise interfere with the main rails. so it will be seen that the l-olliuir stock can pass over the cross in quictly and without iar.

in some instances, and as illustrated in Fins. l and 5. fl provide a crossing con structed of rails of a. peculiar formation. 'lhe said rails comprise a head or tread 7 having the inner face thereof Iahbeted to form a continuous rightangular depressed portion 8. The main body, or lower portion of the rails is enlarged and flares outwardly from its rightangular groove 8 to provide an enlarged base 9. The inner face of the said base is preferably scalloped as designated by the numeral 10, the same being provided to afford a certain amount ,of elasticity as well as to permit the crossing to be firmly secured within the road bed.

The numeral 11 designates the auxiliary rail which is "positioned within the right angular recess 8 of the main rail 7. The auxiliary rail, is inclined or flared upwardly from its point of connection with the rail proper, beyond the crossing, so as to provide the central portion of the said auxiliary rail or that which is attached to the crossing proper, with a smooth bearing face. This bearing face is also adapted to receive the flanges of the wheel and to elevate the wheel proper above the head of the rail. It is to be understood that the transversely arranged auxiliary treads are arranged in a plane parallel with each other, so that no interruption occurs when the said auxiliary rails are in position, and consequently the rolling stock passes over the crossing without contacting with the main rails, and this avoids the thumping of the heels at the cut away portions of the said rails. The auxiliary tread 11 has its lower face provided with elongated slots 12. the said slots being vertically disposed and being arranged to register with openings formed within the main rails 7. By providing the member 11 with elongated slots 12 it will be apparent that by merely loosening the retaining elements which secure the auxiliary rails to the main rails the said auxiliary rail may be raised, strips of suitable material may be inserted within the lower face of the auxiliary rail and the horizontally straight portion of the continuous groove or depression 8 thus shoring the auxiliary railto a desired position with relation to the tread of the main rail.

Tn Figs. 6 and 7 of the drawings, the rails are provided adjacent their heads and upon one of their sides with a continuous longitudinally extending groove. The sides of the rails are curved outwardly to provide an enlarged base, and the base is formed with a continuous longitudinally extending depression 10. The auxiliary rails 11 are adapted to be seated within the grooves upon the side or face of the rails. the auxiliary rails being provided with flanges 14. These flanges terminate at a suitable dis tance away from the right angularly con nected main rail members, the terminals of the flanges being flared outwardly and downwardly, as designated by the numeral 16. The auxiliary rails are provided with transversely arranged elongated openings through which pass the bolts 17 that coact with the nuts 18, whereby the said auxiliary rails may be shimmed to compensate for any wear upon the same.

In Fig. 8 of the drawings, I have illustrated a rail of the construction similar to that described in connection with Figs. 4: and 5. In this instance, the auxiliary rail 19, is integrally formed upon its outer face .with a flange 20. The auxiliary railis secured to the main rail in any desired or pre fer-red manner.

Having thus described the invention what I claim is 1. In a railway crossing superposed rail sections consisting of a plurality of mean rails formed right angularly and in one' piece and having continuous grooves Q'Xlil ling longitudinally of the inner faces of the said rails, and auxiliary rails formed right angularly and in one piece adapted to be received .in the said longitudinally extending grooves, each of the auxiliary rails having the upper faces of its termmals tapered downwardly and having the inner faces flanged, the terminals of the said flanges being curved longitudinally, and means for sustaining the auxiliary rails upon the main rails.

2. In a railway crossing superposed rail sections consisting of a plurality of main rails formed right angularly and in one piece and having continuous grooves extending longitudinally of the inner faces of the said rails, the sides of the said rails being curved to form enlarged bases, the said bases being each provided with a centrally arranged longitudinally extending depression, and auxiliary rails formed right angularly and in one piece adapted to be received in the said longitudinally extending grooves, each of the auxiliary rails having the upper faces of its terminals tapered downwardly and having the inner faces flanged, the terminals of the said flanges being curved longitudinally, and means whereby the said auxiliary rails may be shimmed to retain their bearing faces at a predetermined distance fronrthe heads of the main rails.

3. In a railway crossing superposed rail sections consisting of a plurality of main rails formed right angularly and in one piece and having continuous grooves extending longitudinally of the inner faces of the said rails, and auxiliary rails formed right angularly and in one piece adapted to be received in the longitudinally extending grooves, each of the auxiliary rails having the faces of its terminals tapered downwardly and having the inner faces flanged, the terminals of the said flanges being curved longitudinally, the said auxiliary railsbeing further pr.0vided with vertically snstgliliing 7 opennfgsyeglstermg nt-h opemngsnfth main ra11s permlftlng a rrauge'd elongated ,shinnn'ing of th'suid auxiliary rails m 1-c t'ujn their bearing faces atapredteiunined distance from the head of the maiumuils, 11nd means passmg through the @101 uted h upmimgs: and Openmgxq 1n the mam 111-115 for 'mils.
